Upgraded our Solaris 8 and 9 servers from 3.0.2a to 3.0.3.

After upgrading any user that was in more than 16 Unix groups wasn't able to 
map any drives.  I get this error in the log file:

[2004/05/04 12:23:30, 0] auth/auth_util.c:get_user_groups(695)
  get_user_groups: failed to get the unix group list
[2004/05/04 12:23:30, 0] auth/auth_sam.c:check_sam_security(260)
  check_sam_security: make_server_info_sam() failed with 'NT_STATUS_NO_SUCH_USER'

I tried increasing the kernel parameter ngroups_max from 16 to 32.  I was able 
to map drives, but this breaks NFS.

Any idea what has changed from 3.0.2a to 3.0.3?  Is it a know bug?
